FUEL ECONMIZER AND DEOARBONIZING DEVICE.

v This invention relates to a fuel economizing and decarbonizlng devicefor internal combustion engines, and my invei'itl'o'n aims to furnish anattachment that may be easily and quickly installed on an internalcombustion engine to supply heated air, Water", steam and oil vapor tothe intake" manifold connection of the engine, to commingle' With theusual supply of fuel and increase its combustion properties and decreasethe, carboniz'ing' effect of the fuel the cylinders or combustionchambers of the en ine. It is awvellknowniact that if Water, vapor orsteam is introduced into the cylinders or combustion chambers of anengine. that carbonizhig vvi'llbe reduced to a Ininirrnnn, iit'no'tcon'ipletely eliminated, and that theaddition of steain and Water vaport(i engine" tuel places it in a better condition for com-- bustion. isalso a wellhno'wnfact that the introduction of air is beneficial and.increases the volume of fuel, while viapor" provides better lubricationand also contributes towards bet-tel" combu tion, especially whencertain fuels are used.

h-iy invention further ahns to provide a novel manifoldconnectioirthatma he in"- terphsedfbetween the intake man-item of anengineandthe out-let connection of a can h'urete'r, and it is by virtueof my connection thatfvariohs kinds of vapors can be intro duced tocoinnringle With the engine fuel'as itpassesfrom the ca rhure'ter to thecylinders 01 combustion chambers of the en g'ii re.- The manifoldconnection i i'a clud'es a novel mixing chamber and valve controlledinlet" connections; It is by virtue of these inlet connectiohsthat themanifold oonnectioi'a is well braced arid supportedrelative to anengineMy invention Will he hereinafter specifically described.- and thenclaimed,and reference wiu'mw be had to the drawing, \V-llQIB- 111 Figurel isa side elevation of an internal couil tion engine equipped with mydevice; Fin: 2 is a' vertical sectional view of the ni'anifoldconn'e.ction.- and t Fig. 3 is a vertical sectioi'ial View of the mixingelm-inter of the manifold connection. In the drawings, the referencenumeral 1 denotes a cylinder block having a crank case- 2, an exhaustmanifold 3, an intake inanifold 4, a carbureter 5 having an outletconnection 6, and a throttle 7 in the carbureter outlet connection 6,which throttle is articulated with a pedal arrangement 8 for adj ust'ingthe throttle. When the engine" forms the power plant of an automobile orother driven motor vehicle, the pedalfl is ordinarily located on thefoot board "9 of the automobile and above the foot hoard. is a dash 10,which Will again be referred to Interposed between the carburetor outletconnection '6 and 'the'intake manifold 4 is the lo'iverangular end 11 ofa vertically" disposed jacket 12, said jacket extending upwardly at theouter side oft-he intake manifold 4 With its upper end inturne'd andprovided with a cylindrical head 13 directly above the exhaust manifoldThe jacket 17 may be made in'se'ctions suitably connected-together andthelovver' end o-f t'he jacket can be hired in position'without anydanger of gas lealrage betlweenfhe carburetor and' the intake mani'l o'd. In the acket l2 and suitably spaced from the Walls thereof is aconduit 14 which cx tends throughout the-length of the acket and has itslower end communicating with the intake inai'i'ifold 4 and thecarbureter outlet connection 6 by a series of upper and lower openings1'5, =th-e upper openings ali'rr-in'g with the lower openings so thatfuel may pass through the lower end of the conduit from the carburetorto the intake manifold 4. The openings 1'5 serve somewhat as screens orbattles to assist in atomizing the fuel from the carbureter, and sincethe Walls of the openings 15 will be heated from the jacket 12, the fuelpassing through the openings 15 Will be vaporized.

.On the upper end of the conduit ll; Within the cylindrical head 13' isa cylindrical rniX- ing chamber 16 having a plurality-of radiallydisposedconnections 17 with the head 13 and the connections 1.7 arepreferably four in number. First, there is a connection for an airsupply pipe 18 having a valve 19 operatable from the dash 10' by a rod20. An'otl'ie r' of the connections 17 communicates with the crank case2 by anoil vapor supply pipe 21 which has a valye 22operatahle'by a rod23 from the dash 10 Mounted ontop ot'tlie cylinder block 1 or suitablysupported adjacent thereto a (30111- biired'water boil'e'r', and.starn'generator in the form of 'awvatr tank or reservoir 241mlrounded by ajacket 25. The jacket 25 has pipe connections 26 and 27 with the exhaustmanifold 8 so that the exhausted or burned. gases from the engine maycirculate through the jacket and heat the Walls of the water reservoir24- by conduction. On the pipe 26 is a valve 28 operatable by a rod 29fromv Connecting the top of the water reservoir V 24: to one of theconnections 17 of the mixing chambers 16 is a steam supply pipe 3 1having a valve 35 operatable by a rod 86 from the dash 10, andconnecting the bottom of the reservoir 2% and another of the connections17 of the mixing chamber 16 is a water supply pipe 37 having a valve 38operatable by a rod 39 from the dash 10. V

The lower end of the jacket 12 is connected by a pipe 10 to the exhaustmanifold 3 and the top of the head 18 is connected by a pipe 11 to theexhaust manifold 3 so that exhausted or burned gases from the engine maycirculate through and heat the conduit 14 and the mixing chamber 16.

In the conduit 1% is a throttle 42 connected by a link 43 to thecarburetcr throttle 7 and a rod 4A is connected to the throttle 42, sothat the throttles 7 and 1-2 may be actuated in synchronism by eitherthe pedal 8 or the rod 14.

Since the conduit 141- is heated throughout its length any wateradmitted to the conduit will be vaporized and vapors, air and steam willbe heated, so that when any of these vapors reach the lower end of theconduit they will be in condition to commingle with the engine fuel andpass into the cylinders or combustion chambers of the engine. With allof the mixing chamber connect-ions valve contr lled it will be possiblefor the operator of an automobile to govern the admission of vapors tothe intake manifold according to the performance of the engine andaccording to the fuel used for the engine. Since the beneficial resultsattained by using various kinds of vapors are known, it is thought thatthe operation and utility of my device will be apparent without furtherdescription, and while in the drawings there is illustrated a preferredinstallation and construction, it is to be understood that my inventionis susceptible to such changes as are permissible by the appendedclaims.
